Delphi TStringGrid multi select, determining selected rows

delphi rows selected tstringgrid

Is there anyway to determine which rows are currently selected in a multi-select TStringGrid, or a TCustomGrid for that matter. A property would be ideal.

I know that there is the gdSelected property that gets set in the DrawCell event, 

procedure DrawCell(ACol, ARow: Longint; ARect: TRect; AState: TGridDrawState);

I can check AState for gdSelected, and keep track of this in an array somewhere, but this seems kludgey.

I guess you are talking about a range-select string grid, that is, a string grid with goRangeSelect in Options. Then you can use the Selection property. This is (essentially) a TRect in which you can find the upper-left and lower-right cell in the range selection.
